How to Boil Chicken and Shred:

You can buy a rotisserie chicken and shred the chicken for an easy way to make this dinner. However, we have the perfect post on How to Boil Chicken Breasts that is just as easy. Plus it is a great way to save money.

I am using cooked chicken in this recipe to make it a very simple meal. In my family I like to cook chicken in huge batches, freeze it, and save it for simple dinner ideas.

However, you can easily cook your chicken in the crock pot. See Crock Pot Shredded Chicken.

Ingredients needed - chicken breast, alfredo sauce, minced garlic, salt and pepper, penne pasta, mozzarella cheese, parmesan cheese, parlsey

Ingredients: 

  • Boneless Skinless Chicken Breasts, Cook the Chicken and then Shred
  • Alfredo Sauce ( I really like Bertoli brand but definitely use your favorite type)
  • Minced Garlic or garlic powder
  • Salt and Pepper
  • Penne Pasta
  • Shredded Mozzarella Cheese
  • Parmesan Cheese
  • Parsley (optional)

How do you make Crock Pot Chicken Alfredo Pasta Casserole? 

  • Combine Ingredients – First in a large mixing bowl, combine the Alfredo sauce, water, salt, pepper and minced garlic.
  • Add Pasta to Mixture – Next stir in the penne pasta. Make sure the pasta is completely coated in the sauce recipe that you created.
Mixing the pasta in with the alfredo mixture.
  • Spray Cooking Spray – Then spray your favorite slow cooker with a non stick spray. This prevents sticking so that serving this recipe will be easier.
  • Layer Ingredients – After this, carefully place half the pasta mixture in the bottom of the crock pot. Then place half of the fully cooked chicken on top.
  • Top with Cheese – Next top with 1 cup of the mozzarella cheese and ⅛ cup pf the grated parmesan cheese.

  • Continue Layering – Then add the pasta mixture again using whatever is left. Then layer on top with the remaining chicken. Then top with the cheeses again (the same measurements).
  • Cook Chicken Alfredo – Cover and cook on low for approximately 2 ½ to 3 hours.  You can also try cooking on high for only 1 1/2-2 hours. Cooking time will vary.
The process of layering ingredients in the crock pot
  • Add More Cheese – After it slow cooks, top the entire casserole with 1 more cup of mozzarella cheese.
  • Serve and Enjoy – Place the lid back on to allow this cheese to melt.  Finally, top with the fresh chopped parsley and serve immediately.

What to Serve with Chicken Alfredo:

I like to keep things simple when I prepare this recipe. 

  • Steamed Broccoli – We love to make steamed broccoli with this recipe. Since Chicken Alfredo is a hearty meal, I like to keep the side light.
  • Garlic Bread Cheese Sticks – You definitely need to serve garlic bread with this meal. We love dipping our bread in the alfredo sauce.
  • Caesar Salad – Complete this meal with a side of Caesar Salad. Easy to make with simple ingredients.

Variation Ideas:

  • Add in Vegetables – Add in spinach, broccoli, sun dried tomatoes, or mushrooms for additional flavor.
  • Change the Pasta – We love changing the pasta to what we have on hand. Bow tie pasta or rigatoni noodles would work great for this recipe.
  • Change the Cheese – For a different flavor change the cheese to Romano or asiago cheese.
  • Add in Shrimp – Add in some shrimp or replace all the chicken with shrimp.
  • Other Meats – If you like a savory flavor, mix in some bacon or some prosciutto.
  • Fresh Herbs – If you have some fresh herbs it would a great addition to this casserole. We recommend chives, thyme or fresh basil.
  • Ravioli – Instead of using penne pasta, you can use cheese ravioli or tortellini for that extra cheesy flavor.

Tip for Chicken Alfredo Pasta Casserole:

  • Cooked Chicken – This is a great recipe to use leftover chicken or get a rotisserie chicken.
  • Shredded Cheese – We recommend using freshly shredded cheese. The pre-shredded cheese has other ingredients that may cause the cheese not to melt as well.
  • Alfredo Sauce – We love this recipe because you can use jar alfredo sauce. But you can easily make your own.

How to Bake Chicken Alfredo Casserole:

If you would prefer to bake your Chicken Alfredo Casserole, it is just as easy and you use the same ingredients.

  • Preheat oven to 375 degrees. Coat your pan with a cooking spray to prevent your casserole from sticking.
  • On your stove top, heat your skillet to medium high heat. Once you have your skillet medium heat add your alfredo sauce, cooked chicken, and the remaining seasoning and heat together.
  • Cook the noodles while your sauce is heating.
  • Once your noodles are done cooking, mix together with the alfredo mixture.
  • Then place in baking dish.
  • Top with cheese and bake for 20 minutes uncovered.
  • Serve and Enjoy this pasta bake.

This chicken alfredo bake is easy to make!

How to Store Leftovers for Easy Chicken Alfredo Casserole:

To store leftovers, place in an airtight container and refrigerate. This chicken alfredo will last up to 3 days if store properly.

To reheat, place in a microwave safe dish and reheat in the microwave. Heat in 1 minute increments so everything heats thoroughly.

  • Easy Recipe – Ingredients are easy and making it in the crock pot makes this a perfect weeknight meal.
  • Create a Second Meal – If you have leftover chicken, use it to make this recipe. Most of the time all I need to get at the store is the jar of alfredo sauce.

    Oh I love the idea of caramelized onions!

  2. Deborah says:

    One poster commented on how crunchy the edges got and that was honestly my favorite part! I forgot to lower the crockpot to “Warm” and left it on “Low.” Loved, loved the ease of this, the taste was amazing, got tons of compliments. I made one addition. I like onions and I caramelized one whole onion and about an hour before the cooking time was done, I sprinkled the onion strings all over the top of the dish and it added another layer of flavor. All in all, this will go into my “repeat recipes” file. And this recipe is perfect for using whatever you have in the fridge. Delicious!

    I did mine different as I did not have every ingredient on hand… I used uncooked boneless skinless chicken breasts I did not cut up or shred.. I sprayed down my crockpot and placed 6 chicken breasts in the crockpot…I then used 3 Jars total of alfredo sauce.. 2 jars was 4 cheese alfredo and the last jar was roasted garlic alfredo sauce and i poured them over top the chicken and instead of adding some water as i normally would for dishes in the crockpot eh i wasn’t too keen on that one so I poured some milk in and mixed with the alfredo sauces put lid on and cooking now on high… I make a chicken pasta alfredo bake in the oven similar to your recipe and it is very delicious thanks for sharing your recipe…. I will update n let you know how my dinner turns out later on :^)

  4. Chuck says:

    5 stars
    Absolutely love chicken Alfredo. Only difference between yours and mine is I go through the trouble to make my Alfredo sauce from scratch. Takes awhile but it’s worth it!

  5. Beth says:

    4 stars
    Tastes delicious! Edges got too crunchy even with shorter cooking time. Also needs more Alfredo sauce.

  6. Rudita C Andrada says:

    Thank You and God Bless

  7. Carrie Barnard says:

  12. Laura says:

    5 stars
    This casserole was very easy to make and turned out scrumptious! My husband loved it. I’m looking forward to making it again for the entire family.

  13. Carrie Barnard says:

    Yes, as long as all the ingredients can fit into your crock pot.

  14. Jan says:

    Can this recipe be doubled?

  15. Adrianna kowalski says:

    5 stars
    Five stars …so juicy and great tasting plus very simple to make! My family enjoyed and thought and slaved over the hot stove all day~I think NOT??Thanks again

  16. Carrie says:

    You should not need to add more water with whole grain pasta and the cooking broth should work great in this recipe. I hope you enjoy it!

  17. Lois says:

    I’m using whole grain pasta. Do I need to add more water?
    I also decided to try and use the broth from cooking the chicken because I used Better
    Than Bouillon and wanted the extra flavor. Hope it works!

  18. Carrie says:

    I would make this on the slow cooker setting and the time would be the same. Thanks.

  19. Marilyn Thomasson says:

    I have a Power LX air fryer that slow cooks can I use it and how long would I cook it

  20. Kathryn Canty says:

    5 stars
    Really good and simple!

  21. Carrie says:

    Yes, you can use a rotisserie chicken. I would use 2 cups shredded chicken and eliminate the salt from the recipe.

  22. Martha says:

    Have you used a shredded rotisserie chicken with this? How many cups do you recommend if I use that? I’d probably eliminate any added salt if I do that. Thoughts?

  23. Carrie says:

    Yes, you definitely can use a crock pot bag with this recipe.

  24. Laura says:

    Can I use a crock pot bag in the bottom instead of spraying non stick spray?

  25. Carrie says:

    No, you can make this in any size crock pot. Thank you!

  26. Alix says:

    Does it have to be a 6qt crockpot?

  27. Donna Hill says:

    Could you use the broth you cook the chicken in to mix with the alfredo?

  28. Kayla Satterfield says:

    Do you use parmesan cheese that is fresh/shredded or the kind in the plastic jar with the green lid?

  29. Karen belongie says:

    Should the noodles be cooked if making a oven casserole? If it only bakes for 20 minutes.

  30. Rhonda Bratcher says:

    Thank you so much for including the instructions to cook in the oven. My husband says when I cook in the crockpot, it tastes funny. Go figure ?

  31. Elise says:

    Want to double this recipe to feed 12. I assume that adding the cup of water is to aid in cooking the U.N. cooked penne, correct. Will the water make the daily e runny when it is done? I’m hoping it will be creamy and thicker.

  32. angie says:

    how many cups is a serving?

  33. Carrie says:

    Nicole, I would use 1 rotisserie chicken, shredded, for this recipe which is generally about 2-3 cups. Thank you!

  34. Nicole says:

    If I wanted to use a rotisserie chicken for this recipe how much would I need? How many cups would you suggest? Thanks!

  35. marianne says:

    Can I make this without so much cheese added or will it come out dry?
    thank you

  36. Erika Smith says:

    My box of pasta is only 12oz. Would you change any of the liquid ratios?

  37. Carrie says:

    Yes, you can use canned chicken as well. I would use 1-2 12 oz cans based on how much chicken you would prefer. Thank you.

  38. Carrie says:

    The penne is uncooked. Thank you.

  39. Carrie says:

    Sue, I boil the chicken until it’s completely cooked through. The entire chicken will be a white color when it’s done. Thank you.

  40. Carrie says:

    If the noodles are already cooked, I would reduce the water to 1/2 cup and cook in the crock pot for only 20-30 minutes. Thank you.

  41. Sue says:

    How long do you boil the chicken for

  42. David says:

    How about using canned shredded chicken? How much do you think would be needed?

  43. Ale says:

    When you add the penne pasta to the crock pot at the beginning, is it cooked or uncooked?

  44. Carrie says:

    Yes, I think that would work as long as you have a crock pot with a delayed start feature or a timer on it.

  45. Carrie says:

    Yes, I think that would taste good as well.

  46. Sheri says:

    So I cooked the noodles cause I didn’t see to use uncooked til now. How long do I cook it for now?

  47. MW says:

    I don’t care for Alfredo sauce; do you think it would be good with a tomato-based sauce?

  48. Carrie says:

    Yes, I would cook for half of the cook time if you using the high setting. Thank you!

  49. Carrie says:

    Yes, that would be delicious!

  50. Rhonda says:

    Can you make this ahead of time say put it together before you leave and have the timer turn it on later

  51. Carolyn says:

    could you use tortellini or fettuccine noodles instead?

  52. Laurie says:

    Can I cook this on high in the crockpot?
    .

  53. Haley says:

    Hi I’m using gluten free noodles, if I boil noodles first will that mess the recipe up? I’m nervous they won’t cook correct if I put them in uncooked

  54. Carrie says:

    For this recipe, I cook my chicken in the instant pot or boil it. I don’t add any seasoning as it soaks up the flavor of the other ingredients in this recipe when I combine them all for the casserole. Thank you!

  55. Carrie says:

    I wouldn’t do that as the pasta doesn’t take as long to cook as the chicken does so the pasta would be mushy. I recommending using already cooked chicken for this recipe. Thank you!

  56. Mary says:

    Hello.. Can I cook the chicken, and pasta mixture uncooked at the same time? For 6 hours on low??

  57. shannon says:

    What do you use to cook your chicken? Flavor wise.

  58. Carrie says:

    Thank you!

  59. Jenna says:

    5 stars
    I just made this and it was AMAZING!! Even my pickiest kid gobbled it down! And so easy! I cooked the chicken in the crockpot first as suggested and it was so easy to shred. Plus no additional mess. This is a must try for anyone wondering about this recipe. It checks off all the boxes that I look for as a single mom working two jobs and still trying to put homecooked food on the table. Easy! Cheap! Full of flavor! Family friendly! If I could give it more than five stars I would 🙂

  60. Carrie says:

    Nancy – I used a full 16 oz box of penne pasta for this recipe. Thank you!

  61. Nancy Zimpfer says:

    Can you update the recipe to show how much pasta you used?

  62. Carrie says:

    I haven’t tried it Heather. I would cook a little bit longer than normal and it should work out great!

  63. Heather says:

    Has anyone used whole grain pasta in this recipe? That is what I prefer and it takes longer to cook/boil, so I am curious if using whole grain uncooked in this recipe if it would need longer cooking time?

  64. Carrie says:

    Cindy – I would use uncooked pasta also. Thank you!

  65. Cindy says:

    If you cook this in the oven would you cook the pasta or just put it in there uncooked also?

  66. Carrie says:

    On the instant pot, I would cook for half the cooking time recommended for the pasta that you use in the recipe on high pressure and then do a quick release once it’s done.

  67. Shawanda Williams says:

    How long does need to cook in the instant pot?

  68. Carrie says:

    Jennifer – Yes, you can use rigatoni pasta instead of penne. That would work great. Also, yes, you can cook this casserole in the oven. You would still use pre-cooked chicken and layer in the ingredients in a 9X13 baking dish. Then I would bake at 350 for approximately 20 minutes. Thank you and I hope it turns out great!

  69. Jennifer says:

    Making this tonight 🙂
    Can I use Rigatoni pasta instead of penne? Also, can I cook the chicken in the oven first instead of crockpot? How long would you cook the casserole in the oven instead of crockpot?

  70. Carrie says:

    Awesome – I’m glad you liked them.

  71. Carrie says:

    You don’t need to make any other changes but double all the ingredients. I do that all the time as I have a large family.

  72. Carrie says:

    Yes, but I wouldn’t cook the cauliflower rice in the crock pot as it might get mushy. I would cook it separately and then mix it in the sauce once the chicken is done.

  73. Lani Cartwright says:

    I made this tonight! Used Ragu Alfredo sauce & added a bag of California blend frozen vegetables (broccoli, carrots and cauliflower) . superb!

  74. Carol says:

    Could you make with cauliflower rice?

  75. Angelia Davis says:

    I’m thinking I may have to double the recipe as I will be feeding 3 adults and 4 kids all under the age of 9. What changes would have to be made to double it? I’m new at crockpotting and love it!

  76. Carrie says:

    I would cook it for 4 hours on high or 6 hours on low. Thank you!

  77. Darrian says:

    If i was going to cook the chicken in the croc pot first how long would i cook it for?

  78. Carrie says:

    Tracey – Yes! That would be amazing!

  79. Tracey says:

    can you use homemade Alfredo sauce instead of sauce from a jar?

  80. Carrie says:

    Carrie – In this recipe, the chicken is already cooked but the pasta is not. Thank you.

  81. Carrie says:

    The chicken & pasta can both go in the crock pot un cooked?

  82. Carrie says:

    No, just put in uncooked and try to make sure covered with sauce,

  83. Christine says:

    Do you boil the pasta first ?

  84. ashley says:

    Does the pasta need to be cooked?

  85. Pamela says:

    Can this be frozen?
